IGNITION ms'rmuroa Application filed March 27, 1924. Serial No. 702,446.

This invention relates to distributors fori nition apparatus and includes among its 0%- jects a construction and arrangement of parts which will enable the distributor to be produced at very low cost.

Further objects .and advantages of the present invention will be apparent from the following description of a preferred form thereof, reference being made to the accompanying drawings.

In the drawings:

Fig. 1 is a longitudinal sectional view of ignition apparatus including the present invention.

Fig. 2 is a sectional View on an enlarged scale from that shown in Fig. 1 of one of the ferrules or sleeves for receiving a high tension cable.

Fig. 3 is a view of the ferrule shown in Fig. 2, the section being taken on the line 3- -3 of Fig. 1.

Fig. 4 is a sectional View of the cable sleeve shown in Fig. 2 with a fragment of a high tension cable shown in position.

Peferring to the drawings, the present invention is shown in connection with an ignition timer disclosed in the copending application of Zerbie C. Bradford, Serial No. 7 O2,- 459, filed March 27, 1924. This ignition timer includes a cup'shaped housing which rotatably supports a timer cam shaft 22 carryi g a timer cam 21. The cam cooperates with a rubbing block 34 mounted on a breaker lever 31 which is attached by screw to a condenser 26 mounted in any suitable manner upon a breaker plate 23. Plate 23 is supported for rotation concentric with the shaft 22 by means of the timer housing 20 and endwise movement of plate 23 is prevented by a plurality of screws, one shown at 25. Each screw' passes through an arcuate slot in the lever 23 and threadedly engages the timer housing 20. Cooperating timer contacts, indicated in Fig. 1 by the dotted circle 40, are carried respectively by the lever 31 and by an ear 43 integral with the breaker plate 23.

Adjacent the open end of the housing 20 its internal diameter is increased to provide a shoulder against which is placed a nonconducting disk 51 provided with a plurality of cable receiving ferrules or sleeves, one being centrally located as at 52, and the other sleeves, designated by numeral 53 being arranged in a circular row, concentric with the shaft 22. Each sleeve comprises a cup-shaped member 54 having its external diameter reduced adjacent the open end of the sleeve to provide a shoulder 55. The cylindrical side wall of the member 54 is partly punched through in order to provide a plurality of prongs 56 projecting toward the closed end of the cup 54. The cylindrical wall is also deformed to provide outwardly projecting prongs 57 extendin from the cup 54 toward the open end thereof. Each cup 54 is attached to the non-conducting disk 51 by spinning over the upper edge of the cup as shown at 58 in Fig. 3, so that the disk 51 is confined between the deformed edge 58 and the shoulder and the ends of the prongs 57.

The side wall of the housing 20 is provided with suitable aperture through which the high tension cables 60 may extend within the housing 20. Each of the cables is forced into one of the cups 54 until the stranded conductor 61 thereof touches the bottom of the cup. The prongs 56 are caused to be embedded in the insulation of the cable so as to prevent accidental removal of the cable. After the plate 51 with the cables attached is located as shown in Fig. 1, these members are retained in position by a disk 64 which is retained by a wire split ring 65 received by a groove 66 provided on the interior of the housing 20.

The sleeve 52 provides the center terminal of the distributor and is engaged by a leaf spring 70 connected with a distributing block 71 attached to a distributor rotor 7 2 of nonconducting material. The rotor 72 is supported by and driven by the shaft 22 in any suitable manner as by the tongue and groove connection indicated at 73. The circular row of sleeves 53 being each connected with a spark plug of the engine provide-distributor posts which cooperate with the distributing block 71 in order to conduct sparking impulses to the engine cylinders in recurrent sequence.

The construction embodied in the present invention eliminates the use of a conventional distributor head usually constructed of non-conducting material and provided with cable receiving sleeves, each of which is connected to a distributor post. The distributor head is comprised of a relatively large quantity of insulating material since it provides a cap for thetiiner housing and encloses the distributor posts and rotor as Well as providinga non-conducting support for the cable receiving sleeves. It is apparent therefore that a distributor constructed in accordance with the present invention may be produced at a relatively low cost since the conventional distributor head has been replaced by a simple disk of non-conducting material. Furthermore, the cable receiving sleeves provide signature.

the distributor posts thereby eleminating separate elements to serve this purpose.

While the form of embodiment of the presgo ent invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.

What I claim is as follows:

1: Distributing apparatus comprising, in combination, a housing, a nonconducting cover. therefor, cable receiving sleeves extending into the housing beyond the inside of the cover and open adjacent the outside of the cover, a rotor Within the housing and rotatable in the plane of a portion of the sleeves to distribute sparking impulses, inwardly extending prongs integral With the sleeves for engaging the insulation of elec-- trical conductors inserted within the sleeves, and outwardly extending prongs integral with the sleeves for engaging the inside of the cover.

2. Distributing apparatus comprising; in

40 combination, a housing, a removable nonconducting coven therefor, cable receiving sleeves attached to the cover and extending into the housinggbeyond the inside of the cover and open adjacent the outside of the cover,

a rotor withinjthe housing androtatable in the plane of a portion of the sleeves to distributg sparking impulses, and means for retaining the ends of electric conductors Within said sleeves and for maintaining the cover attached to the housing.

3. Distributing apparatus comprising, in combination, a housing, a removable nonconducting cover therefor, cable receiving sleeves attached to the cover and extending into the housing beyond the inside of the cover and open adjacent the outside of the cover, a rotor within the housing and rotatable in the plane ofa portion of the sleeves to distribute sparking impulses, a plate for maintaining the electrical conductors adjacent the' outer surface of the cover and in contact with the sleeves, and means for retaining the plate in position.
